Physical distribution is concerned with the physical transfer of materials in the process of enterprise production, operation and management. Whether the physical distribution is reasonable and fluent has a significant effect on an enterprise. After analyzing the physical distribution and corresponding information in SINOPEC, we build for SINOPEC Physical Distribution Information Database System which follows the fundamental principle of physical distribution and adopts hierarchy structure and customization mechanism. By hierarchy model, Physical Distribution Information Database System Of SINOPEC is composed of three subsystems respectively for corporation headquarter, subsidiary companies, and factories to satisfy the requirements of different application layer. Each subsystem has its own Physical Distribution Information Database where data collection, query, statistic and analysis, and Web distribution are supported by developing the particular application software components. A close relationship is also established among three subsystems to cooperate and share the information with each other. We choose the n-tier Client/Server style for the system architecture, then implement application server and thin client by using MIDAS technique, which facilitates the system to install, config and maintain, and shows the system more portable and robust. On the other hand, we implement asynchronous data transfer tool Data Trans/MQ to integrate the system components. Data Trans/MQ hides the difference of DBMS and can export and import data automatically through proxy mechanism, therefore subsystems can exchange data and share the information flexibly by virtue of Data Trans/MQ. This thesis presents the analysis, design, implementation and some key techniques used in Physical Distribution Information Database System of SINOPEC in detail from the view of software engineering method.
